[PATCHv4 4/4] OMAP3: export chip IDCODE, Production ID and Die ID
From: Eduardo Valentin <eduardo.valentin(a)nokia.com> This patch exports the OMAP3 IDCODE and Production ID to userspace via /proc/socinfo. Die ID is also exported depending on what users pass as kernel parameter. It is same protection mechanism made for x86 product number. So, if user passes "omap3_die_id" para... 10 May 2010 07:40

From: Eduardo Valentin <eduardo.valentin(a)nokia.com> This patch introduce the /proc/socinfo node. Its purpose is to export System on Chip information and specific bits.

[PATCH v2] ad7877: keep dma rx buffers in seperate cache lines
With dma based spi transmission, data corruption is observed occasionally. With dma buffers located right next to msg and xfer fields, cache lines correctly flushed in preparation for dma usage may be polluted again when writing to fields in the same cache line. Make sure cache fields used with dma do not shar... 10 May 2010 07:40

[PATCH 20/25] lmb: Add arch function to control coalescing of lmb memory regions
Some archs such as ARM want to avoid coalescing accross things such as the lowmem/highmem boundary or similar. This provides the option to control it via an arch callback for which a weak default is provided which always allows coalescing.
